Paving bricks, and yes summers here are saunas, hot, hazy and humid, just how I like it - horses and chickens not so much. The flooring already 'sweats' a lot when it's humid, those bricks are darn slippery when damp!
I will likely turn one of my unused stalls into a summer hen house, they are 10x10 and open so I can wrap it in chicken wire to keep out coins, etc, and then still use a big box fan like I do with the horses. Don't know why I didn't think of that at first - duh! It's not like I will be getting any more horses so may as well use the space for my feather babies
